William,
Why are you so confrontational? We are all here to help each other.
As I already said, there is a but relating specifically to dp's plugin handling code tripping up in scenarios where the event input plugin and certain effects plugins are in the same project.
I know this as I have had word from the team at Vienna and motu. It is being fixed and it is motus issue
I know your issue is unrelated beacause it's yours is exhibiting issues under a different scenario.
All of us here are happy to support each other but you need to stop being so aggressive and confrontational and trust that there are guys here who know what they are talking about.
Your issue is specific to your system beacause, let's be honest, you're not the only one using vep for complex projects, and if everyone's setup was broken then there would be 1000s of complaints. You need to methodically eliminate things one by one and you will solve it.
I've just finished scoring a tv series using vep locally and on a slave machine running many many instances of kontakt... No note dropping issues.
You might want to also eliminate specific kontakt instruments as kontakt 5 has some known issues with certain types of scripts, utilised by both ni and third parties.
And if you haven't already, get in touch with support if your troubleshooting is inconclusive.
i know beyond any doubt that your issue isn't the same as the one myself and others on this thread have identified beacause our issues are solved by taking ether dp, event input or the offending audio plugin out of the equation. In fact I made up a project that exchiits the behaviour on one track and not on another routing to the same instrument track within vep, just to demonstrate the issue.
if you want help, explain your issue in detail including all software versions, libraries and plugins running when the problem occurres.
